As technology evolves, so does the craftiness of bad actors online. These villains are always developing new ways to trick people into giving away their information, finances, sense of security, and more.
That's where we, the CTD Help Desk, come in. We're here to help restore your sense of security by giving you the information you need to arm yourself against their attacks. And, of course, we're always here to help you assess whether something is spam, a phishing attempt, or a legitimate email.
Note: CTD will never request your password, although we may ask your permission to reset it in certain circumstances to assist in troubleshooting. Due to a steep rise in phishing attempts, please be vigilant when opening any emails, links, or attachments requesting your credentials.
Let's start by going over the differences.
- A spam email is when someone sends out bulk email to a list of recipients that didn't opt into that list.
- Marketing emails are often marked as spam even though they are actually legitimate emails (if you want to unsubscribe, it's best to click the Unsubscribe link at the bottom of the email - companies are required to include an Unsubscribe link).
- A phishing email is when someone is trying to steal your information. Some common scenarios include: asking you to click a link, asking you to open a file, pretending to be someone else and asking you to send money, etc.
What to look out for
Now let's go through some common examples so you can familiarize yourself with what to look out for.
This one is an easy one. The email address is just a series of numbers with an equally suspicious looking domain name. It has no subject, no body content, and simply contains a suspicious file attachment. Report and delete it!
In this example, we've blocked out some of the staff names, emails, and organization names, but the bad actor did use legitimate CEO names and organization titles, making it harder to detect. However, there are some easy flags to spot.
- An easy flag is when the sender's email address doesn't match the expected one. If you see an email from Jane Doe, the CEO, but her email displays as <email@example.com>, it's probably not actually from Jane. In this example, we can see that the actual email address does not match the legitimate email address of this staff person. If it did match, but still sounds suspicious, we recommend contacting that staff person directly via phone call to verify if the email was legitimate or not.
- You can also see the banner we've put in place to warn users when the display name matches that of a real staff member, but the email address is different and originates from outside our systems. (As a side note, sometimes bad actors will put in fake flags that look very similar to ours. They do this to throw you off and make it seem legitimate, but stay vigilant!)
The rest of the email could easily be legitimate save for those red flags. If you did happen to respond, likely this bad actor would text you asking you to purchase several gift cards or wire money to some nefarious bank account.
This one is particularly tricky. We've blocked out the name, email address, and signature because they're actually legitimate ones from another organization. However, in this case there are a few flags to pay attention to.
- This email is from someone the recipient had never interacted with.
- The subject line is pretty ambiguous and informal for an email relating to some kind of invoice.
- The attachment is a suspicious .eml file.
Likely in this case, a legitimate user of another organization had their account hacked and a bad actor is sending out these phishing emails from the legitimate user's account. However, if it was from someone the user was familiar with, we would recommend contacting that person directly via phone call to verify if it was a legitimate email or not.
This one is even more tricky because the bad actor has copied the template of a legitimate Microsoft password reset email. At first glance, it looks like a legitimate email, but don't be fooled!
- If you perform an internet search for the email address of the sender, you won't find it on any of Microsoft's web pages because it is not an official email.
- If you hover over the link, you'll see that it's clearly not a Microsoft hyperlink and instead a suspicious website:
Report and delete it!
We see variations of this phishing attempt most frequently. Similar to the last example, bad actors will use similar templates to legitimate emails, but they are really all just wolves in sheep's clothing. Some of them are so well crafted that they'll include legitimate links to a third party company's Privacy Policies or Terms and Conditions pages, just to throw you off. Let's look at some of the flags for this email:
- A fax message email is suspect unless you're expecting one from a verified online fax provider (in which case, you should contact the provider directly to confirm if the email is legitimate or not).
- The sender appears to a phone or fax number, but the email address is suspect and unrecognized to the user. If it was a recognized email address, the user should contact that person directly (perhaps by known phone number) to confirm if the email is legitimate or not.
- The header image in the email is for SharePoint (which is a Microsoft product), but the email is signed by a different organization.
- When we hover over the "Print or Preview Fax" button, we see that it goes neither to SharePoint nor to the fake organization's website, but instead goes to an AirTable link. If you clicked on that link, likely it would take you to an AirTable page with yet another link to a suspicious website that would ask you to log in with your Microsoft account, thus submitting your credentials to the bad actor's collection of stolen account credentials.
This one is crafty in that you may see it and think, "Hey, I didn't order anything! My credit card number must have been stolen!" And then if you click on the links to contact Amazon, you'll be redirected to a malware site where these bad actors may actually pull your credit card or other personal information from your browser's stored data. But remember: stay vigilant!
- The sender address is suspect. Upon closer inspection, you'll see it is not a real Amazon email - it has a zero instead of an "o" and it ends with "group".
- If you copy and paste the links into virustotal.com, you'll see at least one malicious site flag.
- As an extra precaution, you could also check with your credit card company to see if any actual fraudulent charges were made (unlikely in this case, but it doesn't hurt to check).
If you feel confident determining whether an email is legitimate or not, feel free to do the following:
- For spam emails:
- If it seems like a legitimate marketing email and the Unsubscribe link looks normal, click to Unsubscribe yourself from the list (sometimes you may need to reply with "UNSUBSCRIBE" in the subject and/or body of the email).
- If it is an illegitimate spam email, mark it as Junk.
- For phishing emails: Report it, then delete it.
However, if you have any slight doubts, please absolutely contact the Help Desk. It's better to be safe than sorry. And if you did happen to succumb to a bad actor's tricks (we've all had those moments - it happens to the best of us), please call us immediately so we can work with you to protect your account.
